COAL-OIL STOVE.

SPECIFICATION forming part of Letters Patent No. 416,238, date]. December 3, 1889. Application filed July 15, 1889. Serial No. 317.526. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE ROBERTS, a subject of the Queen of Great Britain, residing at the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented new and useful Improvements in Coal-Oil Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same.

, parts, which are absolutely necessary the one to the other-via, the lamp or heat-generator and the stove proper, in which the heat is utilized; and the object of my invention is the construction and arrangement, with the stove proper, of an odorless lamp or lamps which will burn (even a common or low grade of coal-oil) without smoke, gas, or unconsumed vapor and odor, and to arrange the stove proper to be adapted to the said lamp.

A further object of this invention is to form a more convenient form of coal-oil stove, not only as regards the heating of the oven, but also for boiling or heating on the top.

In the drawings hereunto annexed similar letters of reference and numerals indicate like parts.

Figurel is a front elevation of a coal-oil stove'embodying my invention. Fig. 2 is a side elevation of the stove shown in Fig. 1. Fig. 3 is a plan of the'stove shown in Fig. 1 with the top plate at removed. Fig. 4 is a vertical sectional elevational view of the said stove, the sections of parts being taken at line 00, Fig. 1. Fig. 5 is a plan of the oil-reservoir detached. Fig. Gis apart front elevation and part section on line 41', Fig. 5, of the oil-reservoir detached. Fig. 7 is a plan of a portion of the perforated plate 30 and open ing 31, with the wick-tube 25 shown in relation therewith detachedl Fig. 8 is a plan of one of the burner-caps m and wick-tube 25 detached. Fig. 9 is a section of the cap m, wick-tube 25, perforated plate 30, and cover 27, detached, the section being taken at line 00 Fig. 8. Fig. 10 is a plan of the wick-tube 25, showing the relative position of the plates therewith. Fig. 11 is a plan of a portion of the bottom of the oven, oven-door b, and diaphragm f in relation therewith. Fig. 12 is a front elevation of the top part of the diaphragm e, showing opening a therein and damper a The casing a of the stove and oven-door b, as shown, are made of metallic plates or sheets 0, coated with heat-non-conducting material cl, (see Figs. 4 and 11,) or maybe formed in any other desired ordinary manner. Within the casing a are located three diaphragms e,f, and extending from side to side of the casing and united therewith, thus forming, as shown in Fig. 4, a flue h to the chimney 1 an oven-space k, a space 9', and an uptake l to the lamps.'

The diaphragm 6 extends from the top n of the stove to near the bottom of the oven-space 70, leaving an opening at 1 the whole width of the stove. In the top openings at are formed, which are closed or opened at pleasure by a damper a operated by a handle a (See Fig. 12, where a portion of the damper is removed to show the openings at more clearly.) The diaphragms f and g extend from the bottom of the oven-space to near the top of the stove, leaving a space at 2 the whole width of the stove. The tops of these are united together by a plate 3, provided with perforations 4c. This plate 3, if desired, may be made integral with either or both of the diaphragms f and g. 111 the diaphragm g an opening 7 is formed for a current of air to pass into the space g and escape through the perforations 4. This is for the purposes, first, of preventing too much heat being imparted to the oil in the reservoir 9, and, second, the currents of air passing through the perforations 4 are highly heated and cause the products of combustion from the uptake Z to form more intimate contact with the top platen at that part of it situated above the perforations. On the diaphragms e and f projections 5 are formed at various heights, as desired, to enable the bottom of the oven 6, (which is made with a bright reflecting upper surface) provided with perforations b, to be set at; different heights, so that the height of the oven may be pract ically increased or diminished, as de- 5 sired. The upper front part of the stove is formed in part by the casing a and by doors 10, hinged at 11 to the sides of the stove-casing. These doors are in'ovided with mica lights 12, sothat byopcning the doors free [0 access is given to the lights.

13 are diaphragms dividing the uptake 1 into equal parts and providing one part to each lamp or light.

1-lis a damper, which, when placed in a 15 vertical position, being operated by the handle (1, causes the heat of the two lamps or lights in front of it to pass, as indicated by the arrows 15 in Fig. and unite with the heat of the other two lamps or lights. This will be found particularly convenient when it is desired to heat anything very rapidly on the top 71 of the stove, as it concentrates the heat.

1G is a movable plate resting and capable of sliding upon projections 17, attached to the sides of the stove, as shown in Figs. and i. The plate is in its most forward position, with its front edge close up to the top of the diaphragm f, so that the heat will be obliged to pass over this plate and descend into the oven at the back, passing through the perforations S in the bottom (5 of the oven, and by the space 1 and flue 7t escapcs into the chimney 1T.

By placing the plate It) in a more backward position, or close against the diaphragm e, the heat may be regulated, as required, to act more or less upon the food, (be, in thefro'ntor back of the oven.

'18 is an ordinary opcu-work shelf or grating placed on the projections 5 above those on which the bottom (5 is placed. This is for the food, the, and vessel in which the food is placed to rest upon, thebottom (5 serving as a reflector to reflect the heat to the under surfaces of the vessel containing the food, dze.

\Vhen the oven is not in use and the top a is only required to heat upon, the damper a is set to uncover the openings (1, and allow the products of combustion to pass directly into the top of the flue h to the chimney The oil-reservoir 9 isattached at the bottom of the stove, in front. It consists, as shown, of a rectangular inclosed casing having an ordinary titling-hole 19 and openings 20, one each for the lamp-wicks 2]. to pass down through into the oil. Each of these openings is surrounded by a flange 22,10 guide and hold steady and tightly a sleeve 23 inserted therein. These sleeves extend to or nearly to the bottom of the reservoir, except on one side, where, by making one side shorter, an opening BI is formed for the wicks 21 to pass out and extend along upon the bottom. The ob- 6 5 ject of the sleeves is to preventthe larger part of any vapor or gas formedin the reservoir from passingup the wick-tubes and acting on the flame of the lamps or lights. Should any vapor or gas be formed, it will be able to escape by the filling-hole 19, which is provided with a loose cover only suflieiently tight to prevent dust entering, but not air-tight. Thus the said hole becomes a vent also for any prcssu re of accumulated gas or vapor formed within the reservoir 9.

it; is a flange formed on the reservoir. To this ls titted a covcri'i. (See Figs. 1, 4, and 9.) In this cover (see Fig. U) the wick-tubes 25 are inserted and soldered, so as to be practically in one piece therewith.

is a flanged diaphragmhaving openings through which the wick-tubes pass and are soldered. To this are attached deflector. 2t in'eferably one on each side, and bet-ween the inner flanges of the deflector is held a perforated plate 30, having open in 31 for the wicktubes to pass freely through. The deflectors cause the air going to the flames of the lamps or burners to pass as shown by the arrows in Fig. 4-, thus preventing the flames from bein g acted directly upon and caused to smoke, &c., by currents of air in the place in which the stove is situated. On the upper side of the deflectors are situated the burner-caps in. These are provided with inclined plates bent at their upper edges, as shown, Figs. 9 and 10, and provided with perforations 34, so that the air coming to the flames will be divided into three parts on each side of each. flame, as shown by the arrows in Fig. 9, one of which passes over the plate 33, one under it, and the third through the perforations This enables the flame to be made large or small without any smoke, gas, or odor being formed.

1 have illustrated my invention in a stove having four lights; but stoves may be constructed with a greater or less number, and for particular purposes at times it may be desired to only use a portion of the lamps or lights provided. Therefore I furnish a cover or covers 35, (shown only in section in Fi 9,) by which the currents of cold air that would otherwise pass in through the lights or lamps not in use are prevented. In these covers I do not claim any in ventiou. Therefore they need not be more particularly described or shown.

What I claim is as follows:

1. The combination, in a coal-oil stove, of the lamp or lamps with a stove proper, consisting of easing a, having diaphragms c,f, and g, forming flue 71., OVGlI-SpztCG 7t, and space g, said space g having inlet 7, and perforated top 3, having perforations t, movable plate 16, forming a means of regulating the position at which the heat enters the oven, and perforated adjustable bottom 6, by which the height of the oven may be changed, the whole substantially as described.

2. The combination, in a coal-oil stove arranged for the product of combustion to pass directly through the oven thereof 011 its way to the chimney, as described, of a reservoir having sleeves 23 and a vent and lillerhole It),

wick-tubes 25, deflectors 29 and 28, perforated plate 30, and burner-cap m, having inclined perforated plates 33, the whole substantially as and for the purposes set forth.

" 3. The combination, in a coal-oil stove, of the stove proper with a lamp or lampshaving caps on, perforated inclined plates 33, having perforations 34 in their upper curled edges, situated above the level of the upper end of the Wick-tube and adapted to be heated by the flame from the wiok-tube,with said Wick-tube, also the inclined plates 33 being arranged to divide the air passing to the flame into three parts, the Whole substantially as described.

4. The combination, in a coal-oil stove, of
